well..maybe there is some problem with the AC3 T01 2_0ch 192Kbps 48KHz encoded with dvd2avi? i dunno, any help?

If you got an .ac3 file from DVD2AVI it has just been demuxed, not decoded and it will be exactly what was in the original mpeg (or vob) file.
Did you play the audio file in a media player (winAmp, Zoom, WMP classic etc.) to check that it was OK?
Still, some more information would be nice, do you follow any guides, what apps do you use, and what steps to you take to convert the video? If you are using AviSynth then post your script.

I'm not able to find out if you have seperate files (audio & video), but if not you should extract the audio with "virtual dub" to WAV.

Then you should be able to oben the video file & the audio with TMPG and to encode it - then you should hear sound. Sometimes TMPG doesn't like the audio in some files. (Sometimes the reason is just because it is VBR, somtimes not).

If you are finished and have a MPG file, some MPG2 codec won't play 48hz audio.

Please provide the people with some more information.

What you have (AVI, DV, ...) and what you want - what soft u use and so on.

Cheers

extract the audio with "virtual dub" to WAV? What you mean by that? Ive frameserve it with dvd2avi to WAV files. I have the D2V files and and AC3 T01 2_0ch 192Kbps 48KHz files.

Okay,...

Just try to extract the audio (WAV) with virtual dub and then put the avi into video input and the wav to audioinput, then it should work.

Then (when this works) try it with frameserving.

Step-by-step.
